T0 aZZ whom it nmy'concern:

ful Improvement in Straw-Stackers, of whichl the following is a specification.

Our invention relates to improvements in a straw-stacker for which Letters Patent were issued to us dated July 29, 1884, No. 302,588.

The objects of our improvements are to'facilitate and make more perfect the operation of our straw-stacker, as shown in the accompanying drawings, and hereinafter fully described.

The accompanying drawings illustrate our invention.

Figure 1 is a partial side elevation showing the relative positions of the main and auxiliary straw-carriers when raised. Fig. 2 is a similarelevation showing the relative positions of the main and auxiliary straw-carriers when lowered; Fig. 3is aplan of the auXiliary strawcarrier. Fig. 4 is a partial plan of the turntable, showing the mechanism for turning it. Fig. 5 is a vertical section through the center of the turn-table. Fig. 6 is an enlarged vertical section of a portion of the turning mechanism. Fig. 7 is a side elevation of the sliding bearing. Fig. 8 represents a side elevation of the slotted bearing q.

A is a short secondary conveyer, hinged to the forward end of the main conveyer-trough B. Said conveyer is driven by a belt passing over a pulley, a, on its forward shaft, anda pulley, b, on the driving-shaft of the main conveyer.

In this class of straw-stackers as heretofore constructed it has been found that while the straw falling into the straw-carrier trough is retained without trouble, when the building of the straw-stack is fir'st begun, and the trough is level or inclined npward at a slight angle, the straw will fall from the trough to a considerable extent when the stack is nearly finished, and the conveyer-trough is inclined upward at a sharp angle.

For the purpose of causing the conveyer A to assume a proper angle to retain the straw 5o and convey such portion of it to the main conveyerbelt as may have a tendency to fall away, and also to swing downward out of the way of the thrasher straw-carrier O, said conveyer is hinged at its rear end to the main conveyer-trough at c, and its forward end is supported by a pair of braces, d, one end of each of said braces being pivoted on the driving-shaft e of conveyer A, and the other ends of said braces are rigidly secured to the up- 6o per portions of the forward extension-braces,

e', which support the forward end of the main straw-carrier. The turn-table D is rotated alternately in opposite directions by means of pinions on the lower ends of a pair ot' short vertical shafts, f and g. Said shafts are mounted in fiXed bearings ou the turn-table, and the pinions ``engage the internal gear -wheel, E, which is secured to the bed-frame F. The vertical shafts f and g are provided at their up- 7o per ends with screw gear-wheels h and/i, which are revolved by a screw, G, which is secured on the horizontal shaft H. Said shaft has one end bearing in a sliding block, I, which is arranged to move endwise at each partial revolution of the turn-table, so as to cause screw G to alternately engage the gear-wheels h and i, as fully explained in our before-mentioned Letters Patent.

In the stacker shown in said Letters Patent 8o the gear-wheels corresponding to wheels hand t' were rigidily secured to their respective shafts, and said shafts commenced to revolve as soon as engaged by the screw.

For the purpose of causiug the turn-table to rest at the end of each partial revolution, and thereby deposit more straw at the ends of the straw-stack than elsewhere, wheels hand rf are arranged to turn loosely on their respective shafts, and are each held in place thereon by 9o a hollow cap, J, (shown in Fig. 6,) which is rigidly secured to the shaft. A spiral spring,

j, is coiled about that portion of the shaft which is inclosed in the cap J, and the upper end of said spring is secured to the cap, while the lower end is secured to the gear-wheel.

The caps J have each a short arm, k, and the gear-wheels have eachastud, Z, projecting up- Ward so as to engage arm k. Shaft H is revolved by means of the vertical shaft L and bevel gear-Wheels m and n.

For the purpose of keeping. the bevel gearwheel m in proper Working relationv with wheel n when the screw G is shfifted fronr one to the other of the screw gear-wheels h and t', we provide a collar, 0, adapted to turn freely on shaft L, and having on one side a beari ng, p, for the end of shaft H. Shaft H passes also through a bearing, q, Which is slotted laterally, so as to allow a swinging movement of the shaft from side to side,but prevents any' vertical movement of the shaft. bearing I is actuated by means of a tri p-lever, M, and springs r r, and when the screw G is engagedE with either of the gear-wheels' g or h it is' held in engagemen't of one of the Catches, N N, Which hook` over pinsV s s.

In the machine described in' our beforementioned Letters Patent said pins are permanentl'y fixed in the hearing-block I. VVev have found inpracti'Ce as'the'parts' Wear it is necessary` to change the position of the pins; To' meet this requirement we` now secure the pins s s in movable blocks tt, Which are arranged to slide in slots u-u in the bl-'ock I. Said movable blocks and pins are' adjust'abl'y secu-red i'n placeV by screws'vv, which have'bearingsy in the bearing-block I, and pass through screW-threaded holes' in the movableV blocks.

The extensibl'e supports, by means of Which the straw-Carrier' is raised or lowered, are operated by two'Windl-asses, P and R, both being turned simultaneously by a Crank, S, and pinion T. Said pinion is arranged t'o be disengaged from windlass P, Which operatesthe forward supports, e' e'.

For the purpose of insuring the stopping of wi'ndlass P when' the forward end' of the straw-Carrier has been lowered sufliciently, We pivot tov the lower end of the sli'ding portion of said support a toothedpawl, V. Said pawl is pi-voted to the support in such' a position relatively to the gear-wheel of windlass P that When the pawl is brought in contact With said gear-wheel' its teeth are successivel y drawn into' engagement with the teethof the gear when it is turning in a direction to draw the support down, but Will at once'be' thrown out of engagement when the gear is turned in the opposite direction.

I'noperation,when the stack is commenced, the straw-'Carrier is nearly level, as'shown in Fig; 2, and the secondary conveyer A is inclineddownward to allow the main Carrier to come closely up under the straW-carrier of the the bed-frame. l h, the turn-table stops, and the recoil of spring therewith by means 'thrashen vAs the stack Vincreases in height and the-main straw-Carrier is' raised conveyer A is tilted backward, so as to retain and carry backward the straw at the lower end of the main Carrier. When screw G is engaged With gear-Wheel h, said wheel turns loosely on its jshaft, winding up spring j, until stud Zengages arm lc on cap' J.

Shaft f then revolves with Wheel h, and they turn-table rotates until trip-lever M engages a pin, x, projecting from 'When screw G releases Wheel j turns Wheel h on its shaft till stopped by vstud l coming in contact with the opposite l side of arm k. The sl-iding V mains at rest until the wheel has madea revo- When screw G leaves wheel h, it engages wheel fi, but the turn-table relution and its stud Z has engaged -the arm k.

WVe claim as our invention l'. The combination, substantially asA specifi'ed', ofV the principal straw-conveyer, the

- secondary conveyer h'inged thereto, the extens'i'lle supports, and the braces con nectingsa'id j supports and said secondaryconveyer,wh'ereby the relative positions of said primary and secondary conveyers are changed automatically during the rising and lowering of the principal conveyer, for the purpose specified.
